During the Antarctic summer of 2005-2006, Ruben Fijn completed his MSc study biology at the British Antarctic station on Signy Island. His thorough study of the diet of Snow- and Cape Petrels has now been published in the journals Marine Ornithology and Seabird. The Cape Petrel targeted Antarctic krill for food; the Snow Petrels use more fish. Sampling methodology is crucial for obtaining good quantitative diet information.
